A TREATISE ON THE CONNECTION OF 



To oils which contain much inert vegetable matter, 

 it is probable that advantages would be derived from 

 umbrageous green crops without fallowing, equal to 

 those experienced, when hemp is made to precede 

 a crop of wheat ; without which preparation this crop 

 would not have answered the expeftation of the far- 

 mer. 



It is therefore obvious, if ground receives benefit 

 by being overshadowed, the same ground must re- 

 ceive injury by a direct contrary mode of treat- 

 ment.
